Description

Technical Field

[0001] The utility model belongs to the technical field of cantilever beam devices, and in particular relates to a device with a level detection function. Background Art

[0002] When the wet tank cleaning machine cleans silicon wafers, the silicon wafers are placed in a basket, and the robot arm grabs the baskets one by one to clean the silicon wafers in different chemical reagent tanks. The robot arm is generally connected to multiple baskets, and when cleaning silicon wafers, the silicon wafers in multiple baskets can be cleaned at the same time to improve the cleaning efficiency.

[0003] The mechanical arm of the tank cleaning machine is a cantilever beam structure, such as the mechanical arm of the tank cleaning machine disclosed in publication number CN116741664A. One end of the mechanical arm is driven by a motor to move left and right and up and down, and the other end is suspended in the air for hanging flower baskets. After long-term use, the suspended end of the mechanical arm will sag and bend due to long-term hanging of flower baskets, which may easily cause problems such as pressing the baskets or colliding with the tank cover. However, in practice, the drooping changes of the mechanical arm are difficult to detect with the naked eye. If the drooping changes can be detected with the naked eye, production accidents or downtime have already occurred, which greatly affects production safety and production efficiency.

[0026] In order to make the above-mentioned purposes, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] A device with a level detection function, this embodiment is described using a tank cleaning machine. Figure 1 The tank cleaning machine comprises a device body 1 and a mechanical arm 2 arranged on the device body 1, the mechanical arm 2 comprises a cantilever beam type connecting arm 21, the connecting arm 21 is provided with a hanging member 3, and the hanging member 3 can be a flower basket. The above structure is the same as that of the existing tank cleaning machine, and the specific details are not repeated.

[0028] In this embodiment, a horizontal detection device 4 is fixed on the connecting arm 21, and the horizontal detection device 4 includes a trigger hanging member 42 and a metal stopper 43. The trigger hanging member 42 can be swung on the connecting arm 21, and the metal stopper 43 is fixed on the connecting arm 21, and is used to contact the trigger hanging member when the mechanical arm is tilted. The distance between the trigger hanging member 42 and the free end of the mechanical arm 2 is greater than the distance between the metal stopper 43 and the free end of the connecting arm 21. As described above, by arranging the horizontal detection device on the connecting arm 21, when the connecting arm 21 is tilted, the metal stopper 43 fixed on the connecting arm 21 will rotate slightly with the tilt of the connecting arm 21, and the trigger hanging member 42 is vertically drooped under its own gravity and is always in a plumb state. When the tilt of the connecting arm 21 exceeds the set range, the metal stopper 43 rotates to contact with the trigger hanging member 42. At this time, the staff can observe the contact between the two and can timely maintain the mechanical arm 2, avoiding production safety problems caused by the tilt of the mechanical arm 2. In addition, it also avoids downtime, which is conducive to improving production efficiency.

[0029] Further, in order to make it easier for the staff to observe the contact between the metal stopper 43 and the trigger hanger 42, see Figure 2-Figure 4The horizontal detection device 4 also includes a shell 41, a power supply wire 44 and a prompt device 45. The trigger hanger 42 can be rotatably suspended in the shell 41. Preferably, a fixed column 411 can be set in the shell 41. One end of the trigger hanger 42 is sleeved on the fixed column 411, and it remains in a drooping state under the action of its own gravity. One end of the metal stopper 43 is fixed in the shell 41, and the other end is higher than the bottom end of the trigger hanger 42, which is used to contact the trigger hanger 42 when the connecting arm 21 is bent downward. The power supply wire 44 is electrically connected to the metal stopper 43 and the trigger hanger 42, and the prompt device 45 is used to send a prompt signal when the metal stopper 43 contacts the trigger hanger 42. When the metal stopper 43 contacts the trigger hanger 42 (see the state diagram) Figure 3 ), the line between the two is connected, which makes the prompt device 45 send out a prompt signal. After receiving the prompt signal, the staff can maintain the connecting arm 21 in time, which is more convenient to use.

[0030] The power supply wire 44 and the metal stopper 43 and the trigger hanging member 42 may be electrically connected directly or through other metal parts.

[0031] In this embodiment, the metal stopper 43 is detachably connected to the housing 41 , which facilitates replacement and adjustment of the metal stopper 43 .

[0032] Further, referring to Figure 2, a metal connector 46 is fixed in the outer shell 41, and a connecting position 461 is provided on the metal connector 46, and the metal stopper 43 is detachably connected to the connecting position 461; there are multiple connecting positions 461, and multiple connecting positions 461 allow the metal stopper 43 to adjust its installation position according to actual needs, so that the distance between the metal stopper 43 and the trigger hanger 42 can be adjusted according to different detection accuracy requirements, thereby improving the scope of application.

[0033] Furthermore, the metal stopper 43 includes a first metal stopper 431 and a second metal stopper 432 arranged side by side, and preferably, the two metal stops have the same specifications. The first metal stopper 431 and the second metal stopper 432 are connected to the metal connecting member 46, and the bottom end of the trigger hanging member 42 is located between the first metal stopper 431 and the second metal stopper 432. Two metal stops are provided, so that when the housing 41 is installed on the connecting arm 21, it can be installed on any side of the two sides in the width direction of the connecting arm 21 for easy installation. In addition, two metal stops 43 are provided, and when the tank cleaning machine is tilted and the connecting arm is tilted, the trigger hanging member 42 can contact the corresponding metal stopper to detect its horizontality.

[0034] Preferably, the first metal stopper 431 and the second metal stopper 432 are symmetrically arranged about the trigger hanger 42, so that when the outer shell 41 is installed on either side of the width direction of the connecting arm 21, the effect of detecting the horizontality of the connecting arm 21 is consistent, thereby ensuring the detection effect on the basis of facilitating the installation of the outer shell 41.

[0035] In some other embodiments, the metal stopper 43 can be slidably connected to the housing 41. For example, the metal stopper 43 is slidably connected to the metal connector 46 through a slide rail structure and then locked by a locking member such as a screw, thereby achieving the function of adjusting the first metal member.

[0036] In this embodiment, the length of the metal stopper is 4mm-8mm, and the length of the trigger hanger is 3mm-10mm. In this way, the metal stopper 43 has sufficient width to contact the trigger hanger 42, thereby ensuring the contact reliability between the metal stopper 43 and the trigger hanger 42 and preventing the trigger hanger 42 from slipping off the metal stopper 43 due to the small width of the metal stopper 43.

[0037] In this embodiment, the power supply wire is connected to the electrical device of the device, and accordingly, the housing 41 can be integrally formed on the connecting arm 21. Alternatively, a power source is also included, and the wire is connected to the power source, so that when the triggering hanging member 42 and the metal stopper 43 are in contact, a closed loop can be formed between the two. Accordingly, the level detection device can be detachably connected to the connecting arm 21 as an independent device, and the detection device can be installed when the device needs to detect the level of the connecting arm 21. Compared with integrally forming the housing 41 with the connecting arm 21, its detachable connection to the connecting arm 21 is more convenient for practical use.

[0038] In this embodiment, the prompt device 45 includes but is not limited to a light or a buzzer. When a closed circuit is formed between the trigger hanger 42 and the metal stopper 43, the light is always on or the buzzer emits an alarm sound, prompting the staff that the drooping degree of the connecting arm 21 has reached a preset degree and maintenance can be performed.

[0039] The prompt device 45 may be connected in series in a closed loop formed by the trigger hanger 42 and the metal stopper 43, or may be connected to a communication device in the closed loop to achieve wireless control of the prompt device 45 through the communication device.

[0040] In this embodiment, the housing 41 includes a detachably connected bottom plate and a housing cover, which is partially or completely transparent so that the inside of the housing 41 can be observed with naked eyes. Preferably, the housing 41 is made of transparent acrylic material.

[0041] In this embodiment, the housing 41 is provided with a threading hole for passing the power supply wire 44. In addition, the housing 41 is made of an insulating material to avoid the risk of electric shock caused by the housing being charged. The housing 41 is also a sealed housing 41, which can prevent external factors from affecting the metal hanging needle, thereby avoiding the risk of accidental contact between the metal stopper 43 and the metal hanging needle.

[0042] Obviously, the above embodiments of the utility model are only examples for clearly explaining the utility model, and are not intended to limit the implementation methods of the utility model. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made on the basis of the above description. It is not necessary and impossible to list all the implementation methods here. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the utility model should be included in the protection scope of the claims of the utility model.
